Extend an operator class
These topics describe how to extend the functionality
of operator classes. An operator class is the set of
functions that is associated with a secondary-access method. The database
server provides two ways to extend operator classes:
- Extensions of operator classes that the database server provides
When you want to order the data in a different sequence or provide index support for a UDT, you must extend an operator class.
- User-defined operator classes
When one of the existing secondary-access methods cannot easily index a UDT, you might need to create a new operator class.
